which it normalizes into VES format for sending to a VES collector. Please see details in
:ref:`VES Application User Guide <barometer-ves-userguide>`
-One Click Install with Ansible
-------------------------------
-
-Proxy for package manager on host
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-.. note::
- This step has to be performed only if host is behind HTTP/HTTPS proxy
-
-Proxy URL have to be set in dedicated config file
-
-1. CentOS - /etc/yum.conf
-
-.. code:: bash
-
- proxy=http://your.proxy.domain:1234
-
-2. Ubuntu - /etc/apt/apt.conf
-
-.. code:: bash
-
- Acquire::http::Proxy "http://your.proxy.domain:1234"
-
-After update of config file, apt mirrors have to be updated via 'apt-get update'
-
-.. code:: bash
-
- $ sudo apt-get update
-
-Proxy environment variables(for docker and pip)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-.. note::
- This step has to be performed only if host is behind HTTP/HTTPS proxy
-
-Configuring proxy for packaging system is not enough, also some proxy
-environment variables have to be set in the system before ansible scripts
-can be started.
-Barometer configures docker proxy automatically via ansible task as a part
-of 'one click install' process - user only has to provide proxy URL using common
-shell environment variables and ansible will automatically configure proxies
-for docker(to be able to fetch barometer images). Another component used by
-ansible (e.g. pip is used for downloading python dependencies) will also benefit
-from setting proxy variables properly in the system.
-
-Proxy variables used by ansible One Click Install:
- * http_proxy
- * https_proxy
- * ftp_proxy
- * no_proxy
-
-Variables mentioned above have to be visible for superuser (because most
-actions involving ansible-barometer installation require root privileges).
-Proxy variables are commonly defined in '/etc/environment' file (but any other
-place is good as long as variables can be seen by commands using 'su').
-
-Sample proxy configuration in /etc/environment:
-
-.. code:: bash
-
- http_proxy=http://your.proxy.domain:1234
- https_proxy=http://your.proxy.domain:1234
- ftp_proxy=http://your.proxy.domain:1234
- no_proxy=localhost
-
-Install Ansible
-^^^^^^^^^^^^^^^
-.. note::
- * sudo permissions or root access are required to install ansible.
- * ansible version needs to be 2.4+, because usage of import/include statements
-
-The following steps have been verified with Ansible 2.6.3 on Ubuntu 16.04 and 18.04.
-To install Ansible 2.6.3 on Ubuntu:
-
-.. code:: bash
-
- $ sudo apt-get install python
- $ sudo apt-get install python-pip
- $ sudo -H pip install 'ansible==2.6.3'
-
-The following steps have been verified with Ansible 2.6.3 on Centos 7.5.
-To install Ansible 2.6.3 on Centos:
-
-.. code:: bash
-
- $ sudo yum install python
- $ sudo yum install epel-release
- $ sudo yum install python-pip
- $ sudo -H pip install 'ansible==2.6.3'
- $ sudo yum install git
-
-.. note::
- When using multi-node-setup, please make sure that 'python' package is
- installed on all of the target nodes (ansible during 'Gathering facts'
- phase is using python2 and it may not be installed by default on some
- distributions - e.g. on Ubuntu 16.04 it has to be installed manually)
-
-Clone barometer repo
-^^^^^^^^^^^^^^^^^^^^
-
-.. code:: bash
-
- $ git clone https://gerrit.opnfv.org/gerrit/barometer
- $ cd barometer/docker/ansible
-
-Edit inventory file
-^^^^^^^^^^^^^^^^^^^
-Edit inventory file and add hosts: $barometer_dir/docker/ansible/default.inv
-
-.. code:: bash
-
- [collectd_hosts]
- localhost
-
- [collectd_hosts:vars]
- install_mcelog=true
- insert_ipmi_modules=true
-
- [influxdb_hosts]
- localhost
-
- [grafana_hosts]
- localhost
-
- [prometheus_hosts]
- #localhost
-
- [zookeeper_hosts]
- #NOTE: currently one zookeeper host is supported
- #hostname
-
- [kafka_hosts]
- #hostname
-
- [ves_hosts]
- #hostname
-
-Change localhost to different hosts where neccessary.
-Hosts for influxdb and grafana are required only for collectd_service.yml.
-Hosts for zookeeper, kafka and ves are required only for collectd_ves.yml.
-
-.. note::
- Zookeeper, Kafka and VES need to be on the same host, there is no
- support for multi node setup.
-
-To change host for kafka edit kafka_ip_addr in ./roles/config_files/vars/main.yml.
-
-Additional plugin dependencies
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-By default ansible will try to fulfill dependencies for mcelog and ipmi plugin.
-For mcelog plugin it installs mcelog daemon. For ipmi it tries to insert ipmi_devintf
-and ipmi_si kernel modules.
-This can be changed in inventory file with use of variables install_mcelog
-and insert_ipmi_modules, both variables are independent:
-
-.. code:: bash
-
- [collectd_hosts:vars]
- install_mcelog=false
- insert_ipmi_modules=false
-
-.. note::
- On Ubuntu 18.04 the deb package for mcelog daemon is not available in official
- Ubuntu repository. In that case ansible scripts will try to download, make and
- install the daemon from mcelog git repository.
-
-Configure ssh keys
-^^^^^^^^^^^^^^^^^^
-
-Generate ssh keys if not present, otherwise move onto next step.
-
-.. code:: bash
-
- $ sudo ssh-keygen
-
-Copy ssh key to all target hosts. It requires to provide root password.
-The example is for localhost.
-
-.. code:: bash
-
- $ sudo -i
- $ ssh-copy-id root@localhost
-
-Verify that key is added and password is not required to connect.
-
-.. code:: bash
-
- $ sudo ssh root@localhost
-
-.. note::
- Keys should be added to every target host and [localhost] is only used as an
- example. For multinode installation keys need to be copied for each node:
- [collectd_hostname], [influxdb_hostname] etc.
-
-Download and run Collectd+Influxdb+Grafana containers
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The One Click installation features easy and scalable deployment of Collectd,
-Influxdb and Grafana containers using Ansible playbook. The following steps goes
-through more details.
-
-.. code:: bash
-
- $ sudo -H ansible-playbook -i default.inv collectd_service.yml
-
-Check the three containers are running, the output of docker ps should be similar to:
-
-.. code:: bash
-
- $ sudo docker ps
- CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
- a033aeea180d opnfv/barometer-grafana "/run.sh" 9 days ago Up 7 minutes bar-grafana
- 1bca2e4562ab opnfv/barometer-influxdb "/entrypoint.sh in..." 9 days ago Up 7 minutes bar-influxdb
- daeeb68ad1d5 opnfv/barometer-collectd "/run_collectd.sh ..." 9 days ago Up 7 minutes bar-collectd
-
-To make some changes when a container is running run:
-
-.. code:: bash
-
- $ sudo docker exec -ti <CONTAINER ID> /bin/bash
-
-Connect to <host_ip>:3000 with a browser and log into Grafana: admin/admin.
-For short introduction please see the:
-`Grafana guide <http://docs.grafana.org/guides/getting_started/>`_.
-
-The collectd configuration files can be accessed directly on target system in '/opt/collectd/etc/collectd.conf.d'.
-It can be used for manual changes or enable/disable plugins. If configuration has been modified it is required to
-restart collectd:
-
-.. code:: bash
-
- $ sudo docker restart bar-collectd
-
-Download and run collectd+kafka+ves containers
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-.. code:: bash
-
- $ sudo ansible-playbook -i default.inv collectd_ves.yml
-
-Check the containers are running, the output of docker ps should be similar to:
-
-.. code:: bash
-
- $ sudo docker ps
- CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
- 29035be2dab5 zookeeper:3.4.11 "/docker-entrypoint._" 7 minutes ago Up 7 minutes bar-zookeeper

-
-
-To make some changes when a container is running run:
-
-.. code:: bash
-
- $ sudo docker exec -ti <CONTAINER ID> /bin/bash
-
-List of default plugins for collectd container
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-.. note::
- The dpdk plugins dpdkevents and dpdkstat were tested with DPDK v16.11.
-
-By default the collectd is started with default configuration which includes the followin plugins:
- * csv, contextswitch, cpu, cpufreq, df, disk, ethstat, ipc, irq, load, memory, numa, processes,
- swap, turbostat, uuid, uptime, exec, hugepages, intel_pmu, ipmi, write_kafka, logfile, mcelog,
- network, intel_rdt, rrdtool, snmp_agent, syslog, virt, ovs_stats, ovs_events, dpdkevents,
- dpdkstat
-
-Some of the plugins are loaded depending on specific system requirements and can be omitted if
-dependency is not met, this is the case for:
- * hugepages, ipmi, mcelog, intel_rdt, virt, ovs_stats, ovs_events
-
-List and description of tags used in ansible scripts
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Tags can be used to run a specific part of the configuration without running the whole playbook.
-To run a specific parts only:
-
-.. code:: bash
-
- $ sudo ansible-playbook -i default.inv collectd_service.yml --tags "syslog,cpu,uuid"
-
-To disable some parts or plugins:
-
-.. code:: bash
-
- $ sudo ansible-playbook -i default.inv collectd_service.yml --skip-tags "en_default_all,syslog,cpu,uuid"
-
-List of available tags:
-
-install_docker
- Install docker and required dependencies with package manager.
-
-add_docker_proxy
- Configure proxy file for docker service if proxy is set on host environment.
-
-rm_config_dir
- Remove collectd config files.
-
-copy_additional_configs
- Copy additional configuration files to target system. Path to additional configuration
- is stored in $barometer_dir/docker/ansible/roles/config_files/vars/main.yml as additional_configs_path.
-
